Application filed August 29, 1921.

To all whom t may concern.'

Be it known that EARL C. TAYLOR, citizen of the United States of America, residing at leoria, in the county of Peoria and State of Illinois, has invented certain new and useful Improvements in Siphon Starters, of which the following is a specification, reference being had therein to the accompanying drawings.

The .invention relates to siphon starters, and has for its object to provide a device of this character comprising a pumping member for starting the siphoning operation, said pumping member comprising a reciproeating piston within a cylinder, and so constructed that during the siphon starting operation the fluid will not pass through the cylinder' or come in Contact with the reciprocating piston.

A further object is' to provide a siphon starting pump comprising a cylinder, a reciprocating piston disposed in said cylinder and a cap threaded on the lower end of the cylinder and provided with a tapered eX- tension for the reception of one end of a siphoning hose, said cap being provided with a discharge port through which the siphoned material will be discharged during a Siphoning operation.

lilith the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings F'gure 1 is a view partially in side elevation and section ot' the siphon starting device, showing the same inV position for startiug a siphoning operation Jfrom one receplacie to another.

Figure 2 is a perspective view of the base member oi' the siphon starter.

Referring to the drawings. the numeral 1 designates a siphon starter. which siphon starter is oi" a pump type, and comprises a cylinder 2 in which cylinder is slidably mounted a piston 3 carried by a piston rod 1. The piston rod 4 extends upwardly through an aperture 5 in a cap 6 threaded on the upper end of a cylinder 2 and terminates in a right angled portion 7 which forms a handle member adapted to be Serial No. 496,272.

grasped by the operator for reciprocating the piston 3 in a chamber 2a of the cylinder 1. rIhreaded at 8 to the lower end 9 of the cylinder 2 is a hollow base member 10, which base member is provided with a shoulder 11 for limiting the downward movement of the cylinder 2 when the base member is screwed into place. Extending outwardly and preferablyradially Jfrom the base member 10 is a tapered extension 12, which extension has a passage 13 extending therethrough and in communication with the chamber 14 in the base member 10. The shoulder 11 of the cylinder 2 is disposed above the passage 13 and hence does not interfere withthe ilow ot liquid into the chamber 14 during a siphon starting operation. Detachably connected at 15 to the extension 12 is a section of rub". ber pipe 16 which forms the siphon, and through which pipe the liquid 17 in the receptacle 1S is siphoned and deposited in the receptacle 19.

When it is desired to start a siphoning operation, the operator grasps the handle and moves the piston 3 upwardly and recip rocates the same. If he desires to start the siphoning operation rapidly he m'ay cover the discharge port 20 in the base 10 withv his linger, however if he desires to start the siphoning operation more slowly and by continued reciprocation of the piston 3 the siphoning operation will talre place as the discharge port 2O is smaller than the passage `13 through the extension 12. It will be seen that a siphoning operation will be started through the pipe 16 and that the liquid 17 will not come in contact with the pistons 3, whichl is a decided advantage for preventing corro-sion in case of water, acids or heavy oils, and also preventing gum-y ming and sticking of the piston 3.` lf so desired after the siphoning` operation has been started the pipe 16 may be detached at 15 from the extension 12 and the siphon starter used for starting siphoning operations at all places.

From the above it will be seen that ay siphon starting pump is provided which is simple in construction and so constructed that a siphon operation may be started in such a manner that the liquid will not come in contact with the piston. v

The invention having been set forth what is claimed as new and useful is The combination with a siphoning pump comprising a cylinder having a longitudinully movable piston therein, of a base connected to the lower end of said cylinder and having a chamber therein and e discharge pol-t extending through the base and '1n communication with the chamber, said discharge port being of a constant area, a, pipe receiving extension carried by Said base and provided with a passage therethrough, the pipe receiving extensionpassage being of greater diameter or cross Sectional area than 10 the discharge port.
